In the days before slanted top tubes no one worried about standover clearance or the lack thereof.

Standover clearance only became a "thing" after bike manufacturers started making "compact" frames (slanted top tubes) so standover clearance became a feature to sell a bike. Then sales people started "sizing" a bike for customers based on standover clearance like it meant anything. Sizing a bike based on standover clearance is the least professional way to do it.

If the bike fits you when riding then it fits you. Standover clearance or the lack thereof is the last thing I would consider in a fit. Not the first.

For the record, I have short legs. If I can put 2 feet flat on the ground over the top tube then I have standover clearance whether anything is touching or not. On my first racing bikes I didn't even come close to putting 2 feet flat on the ground.
